Memory corruption while processing IOCTL calls for escape operations.
AnalysisAI
Local privilege escalation in Qualcomm Snapdragon platforms stems from an out-of-bounds read (CWE-125) triggered during IOCTL escape operation processing, resulting in memory corruption. A local authenticated attacker with low privileges on an affected Snapdragon-based device can leverage the flaw to achieve high-impact compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Technical ContextAI
Snapdragon system-on-chip platforms expose kernel-mode driver interfaces to userspace via IOCTL (input/output control) calls. 'Escape' operations are a specific class of vendor-defined IOCTL command typically used by graphics or display drivers (a pattern inherited from DirectX-style EscapeCmd handling) to convey custom commands between user-mode components and kernel drivers. The CWE-125 (out-of-bounds read) classification, combined with the 'Buffer Overflow' and 'Information Disclosure' tags, indicates the kernel driver fails to validate input buffer length or offsets supplied through the IOCTL escape parameters, reading past allocated memory and producing memory corruption. The CPE string cpe:2.3:a:qualcomm,_inc.:snapdragon:*:*:* points to Snapdragon-branded chipset components across versions; exact affected firmware/driver builds are enumerated only in the Qualcomm June 2026 security bulletin.
RemediationAI
Patch available per vendor advisory - apply the Qualcomm-released firmware/driver updates documented in the June 2026 Qualcomm Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/june-2026-bulletin.html), and on Android devices apply the corresponding OEM monthly security patch level that incorporates these Qualcomm fixes once vendor builds are published. Because the flaw requires local code execution on the device, compensating controls until patches arrive include restricting installation to Play Protect / managed app stores to limit local attacker code on the device, enforcing MDM policies that block sideloading and developer mode (trade-off: reduced flexibility for power users), and on rooted/test devices avoiding running untrusted native binaries. There is no practical configuration toggle to disable IOCTL escape paths without breaking graphics/display functionality, so patching is the durable fix.
